Carbon disbonding issues....

So i am on my my second TRc frame after my first was warrantied due to the lower pivot attachment came disbonded. After about 100 miles on the new frame I can already tell the same thing in the same place is going to happen and I will require another warrantied frame. I've read the LTc TRc and the XCc all have this same issue in the same exact spot. I've also heard that this might have been fixed on the BronsonC. Anybody have these issues, and if so how many frames have you gone through? At this rate ill be replacing frame and/or rear triangle every 2-3 months!!!! Was this issue actually fixed on the BronsonC as well??? The frame is stronger than anything else I've ever ridden its just this one weak spot that is starting to drive me nuts!

Sounds like if it is a consistent issue there will probably be a fix in the pipeline from the OEM. A reputable mfg will work to rectify an engineering/production error even if it may take time to show up as a fix. Stay in contact with the company and you may be pleased with the results.

Oh trust me I am, I love this bike and SC regardless of this issue. I'm just trying to understand how widespread this issue is as I've seen it on every carbon frame from 2010 on. The rest of the frame and carbon is impeccable and I have absolutely no complaints other than this one area.

I am on my 3rd TRc swingarm the first was an 135mm (V1?) version, the second was an 142mm. This is in the space of 5/6 months. For my 3rd I was considering asking them for an alu version.

It sucks because I love the bike but clearly there is an issue.

I love the carbon but I can't keep having a down bike for 2 weeks every 3 months due to this issue. So from what I've read TRc, XCc, LTc, and NomadC all have the same issues? What about the BronsonC, was anything changed on the pivot point?

Carbon disbonding issues....

Here's what the crack looks like:

That's from the frame that was warrantied. My 2013 frame isn't that bad yet.
It's not a structural crack in the carbon layup. It's a dis/unbonding (as the thread title says) of the threaded metal insert for the lower pivot bolt and the carbon of the rear triangle.

As far as the update on the Bronson frame - it's just something that was mentioned in the 4/1 press release. I'll find the quote in just a sec.

Edit:
Here's the bullet point from the press release:
• Co-molded aluminum hardware on frame pivots: no bonding.

I assumed that meant a fix to this issue.
I mentioned it in the 4/1 thread and I think that's what people are referring to as the fix.

This is what I was referring to. I hope this fixes the issue and I really hope that the same method is used in the 2014 TRc when they do come out. I have a sneaky suspicion that I will end up with a 2014 frameset one day

What do you suspect would happen if you carried on using the frame after this crack appeared? I've not taken one of these apart but I'm assuming from what you're saying that the metal insert would eventually lose any connection with the frame and it'd be impossible to tighten the bottom link, is that correct?

That's what I think would happen, the whole thing would just spin freely with no connection to the rear triangle.

I could feel mine going before I even saw the hairline crack. The back end started twisting under heavy effort and felt sloppy. I suspect this is what it would feel like if the pivot hardware was loose. Checked mine, rode it... still felt terrible. Probably about 2 rides later the crack was visible. I think before you got to the point you couldn't tighten it, you'd be pretty disappointed with the lack of stiffness in the lower link. If the insert is not circular, it might not spin, but it will still feel terrible.

I completely agree with this statement especially if you ride pretty hard and kick the back end out often. If you just XC ride and take time enjoying the trails you should be fine with the crack but it will eventually require a warranty frame and/or rear triangle. But if you bomb the trails it should probably be replaced the first chance you get just in case. The good news is that SC warranty dept is spot on, just email them a photo or two of the crack and a copy of the purchase receipt and they will take care of you.

I thought this was a TRc issue. Is it also an issue with the TBc and TBLTc? I was hoping one would be my next bike.

Don't let this thread deter you at all. The frames are rock solid, provide excellent stiffness and can be put through their paces without any hesitation. This issue isn't with the carbon it's with this one little insert and depending on how you ride some people have never had this issue . I ride my bike fairly aggressive and I expect that's why I see this issue, but it wouldn't stop me from buying another SC carbon bike, not for a second!
